CD 2000

CD 2000: Bipolare Entladungsstrecke
Bipolar Discharge System

The bipolar corona discharge CD 2000 is used to neutralize the charge of a dust or liquid aerosol or even to electrically charge it, as required. For this purpose, a current is set on the positive and negative high voltage source so high that it is still entirely conducted through the corona discharge generated at the tip in the corona chamber, but no (or few) sparks are generated. This current is programmed via the current limitation of the HV power supplies. The voltage limitation is set slightly higher than is necessary for the current determined, such that this current flows under all circumstances (temperature, condition of the electrode). The positive and the negative high voltage supplies and the CD 2000 are independent of one another and are independently adjustable.
